Gene Rv3252c
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Thought to be involved in fatty acid metabolism. Generates octanol and oxidized rubredoxin from octane and reduced rubredoxin. Also hydroxylates fatty acids in the omega-position [catalytic activity: octane + reduced rubredoxin + (O)2 = 1-octanol + oxidized rubredoxin + H(2)O]. |
| Product | Probable transmembrane alkane 1-monooxygenase AlkB (alkane 1-hydroxylase) (lauric acid omega-hydroxylase) (omega-hydroxylase) (fatty acid omega-hydroxylase) (alkane hydroxylase-rubredoxin) |
| Comments | Rv3252c, (MTCY20B11.27c), len: 416 aa. Probable alkB, transmembrane alkane-1-monooxygenase, highly similar to many (see Marin et al., 2001) e.g. Q9AE68|ALKB2 from Rhodococcus erythropolis (408 aa), FASTA scores: opt: 2018, E(): 9.6e-122, (68.6% identity in 415 aa overlap); Q9AFD5|ALKB from Nocardioides sp. CF8 (483 aa), FASTA scores: opt: 1485, E(): 1.4e-87, (56.55% identity in 405 aa overlap); Q9XAU0|ALKB1 from Rhodococcus erythropolis (391 aa), FASTA scores: opt: 1400, E(): 3.3e-82, (62.6% identity in 396 aa overlap); Q9XBM1|ALKB from Prauserella rugosa (490 aa), FASTA scores: opt: 1266, E(): 1.5e-73, (57.55% identity in 410 aa overlap); CAC40954|ALKB4 from Rhodococcus erythropolis (386 aa), FASTA scores: opt: 1190, E(): 9.1e-69, (54.3% identity in 383 aa overlap); etc. |
| Functional category | Lipid metabolism |
| Transcriptomics | mRNA identified by microarray analysis and up-regulated after 24h of starvation (see Betts et al., 2002). |
| Mutant | Non-essential gene for in vitro growth of H37Rv in a MtbYM rich medium, by Himar1 transposon mutagenesis (see Minato et al. 2019). Disruption of this gene provides a growth advantage for in vitro growth of H37Rv, by analysis of saturated Himar1 transposon libraries (see DeJesus et al. 2017). Non essential gene by Himar1 transposon mutagenesis in H37Rv and CDC1551 strains (see Sassetti et al., 2003 and Lamichhane et al., 2003). Non-essential gene for in vitro growth of H37Rv, by Himar1 transposon mutagenesis (See Griffin et al., 2011). Non essential gene for growth in vitro by Tn5370 transposon mutagenesis of H37Rv strain but mutant is more virulent in SCID mice (see McAdam et al., 2002).
